TOSUNE-S20/S20LP
ThG T03LINE-S20/S20LP is an N-to-N high-speed data link network. Implicit token passing avoids tho
possibility of message collision. The TOSLINE-S20/S20I_P Is ideal for real-time control between PLCs, or
between PLCs and Toshiba Adjustable Speed Drives.
TOSLINE-S20LP
The TOSÜNE-S20LP is a high-neliabilHy double-loop
fiber optic system. The T2N CPU module {PU245IM)
has the TOSUNE-S20LP built-in.
The double-loop configuration and the floating
master function allow the TOSLINE-S20LP to
continue data link operation even if a transmission
cable is cut or a Station drops out of the network,
TOSLINE-S20
The TOSLINE-S20 is a bus type data link network.
The transmission media can be either co-axial or
fiber optic cable, according to the application
requirement.
• SN221: Co-axial cable type station for T2E/T2N
• SN222A: Fiber optic type station for T2E/T2N
These station modules can be mounted in any PO
slot, main or expansion rack, of a T2E/T2IM system.
